I agree with the aesthetics that
@heatherB mentioned above. The traditional one looks better in my opinion.
I have the traditional one, and even though I love how it looks, I personally don't find myself reaching for it a lot because:
1. It doesn't lay on my body in the most comfortable way. It's quite rigid, and the combination of the shape along with the strap length on my 5'2" height makes it feel like I'm wearing a box on my hip. The camera bag looks like it would be softer, and lay better.
I usually prefer to wear small crossbody bags (Celine Teen Triomphe, Chanel Square Mini) or "larger" soft hobo bags (really loving the Madewell Essential Curve Suede Shoulder Bag this season) because they feel more comfortable.
2. I have the hair pulling issue that others have experienced. If you're not familiar, there is a button the on strap that is exposed when you wear the strap crossbody, and my long hair often gets caught in it. I now only wear this purse if my hair is in a bun or ponytail.
That being said, I still love how it looks. I considered parting with it earlier this year, but I just couldn't.
